标题: OG17 CR662
最近做逻辑都做魔怔了
遇到了一道题望各位大神解惑


Vargonia has just introduced a legal requirement that student-teacher ratios in government-funded scholls not exceed a certain limit. All Vargonian children are entiled to education, free of charge, in these schools. When a recession occurs and average incomes fall, the number of Children enrolled in government-funded schools tends to increase. Therefore, though most employment opportunities contract in economic recessions, getting a teaching job in Vargonia's government-funded schools will not be made more difficult by a recession.

Which of the following would be most importent to determine in order to evaluate the argument?

A Whether in Vargonia there are any schools not funded by the government that offer childern an education free of charge?
B Whether the number of qualified applicants for teaching positions in government-funded schools increases signnificantly during economic recession.

本人就在这两个选项中纠结。我是这么解释A选项的。
如果有这种免费的非政府建立的学校,那么政府资助的免费学校里学生数量在经济衰退的时候可能不会增加的那么多,因为会被这种私立免费办学的学校给分流,因此,老师相应提供的数量也不会太多,如果要增强,那这种学校不能够出现。

B的话如果应聘的人显著增加,但是需求量如果很大的话,也不会造成difficulty的出现呀
求大神看看我的分析!!!

我的理解是,他说当recession了之后,政府免费教学入学的小盆友会增加。所以找个老师的活儿在recesssion的时候不会变得更难(相比其他受到recession影响而紧缩的职位)。

辣么,主要的argument是,找个老师的活儿不会太难 - 在某种特定的环境下。

b 直击了这个问题,如果申请人数因为recession而倍数增加。那么申请不会 “不会太难”。毕竟说了学生和老师会有一定的比例。需求量再大也难以overcome 这个supply的效果。

a 说了非政府的教育机构,可是主要argument是“找个老师的工作不会太难” 而非“找个在政府里建立的教育机构里老师的工作不会太难”。 所以相对b比较weak。

个人理解,欢迎讨论!

我没有系统看过论坛上的一些推理方法。因此若有不正,不吝赐教!个人觉得 When a recession occurs and average incomes fall, the number of Children enrolled in government-funded schools tends to increase. 属于前提,题干已经说明了,就不能质疑其合理性了。therefore后面的才是结论,评估的是推理的过程,因此A感觉和题目没什么关系

1. 找出argument & line of argument
法律限制政府学校学生/老师比率。经济不好时,政府学校学生人数增加,所以经济不好时政府学校老师工作还是不会更难找。

2. 分析逻辑
两个逻辑事物
A (经济不好时)政府学校老师职位增加(学生人数增加+政府学校学生/老师限制)
B (经济不好时)政府学校老师工作不会更难找。

想像一下,如果和朋友争辩
找茬 - 老师职位是增加,但不一定更好找啊。经济不好时,找工作的人更多

3. 答案
B - 就是这个找茬
A 常见的一个无关。逻辑推理中一般是假设前提已成立,这里就是假设A学生人数增加成立。辩论主要是能否从假设A推到B。偶尔也有找茬说A其实并不成立,但是那样应该说的非常清楚的把A给削弱。
看答案A。即使有别的学校也给免费教学,并不能削弱A。这些别的免费学校平时也是有学生的。经济不好时,去免费学校的学生增加,那可能是所有这些免费学校的学生都会增加。所以假设A还是可以成立的。这个也更符合现实情况。
一般情况下,不要去考虑推翻假设。如果假设都推翻了,那这个辩论不就是浪费时间比较低质量的吗?


关键是找到A->B,然后集中逻辑思维在A->B来考核答案
